Question: The Italian theorectical physicist was the first to discover Fano resonance which is what?

Context paragraphs:
Ugo Fano: Ugo Fano {'1': ", '2': ", '3': 'ForMemRS', '4': "} (July 28, 1912 – February 13, 2001) was an Italian American physicist, notable for contributions to theoretical physics.

Isidor Isaac Rabi: Isidor Isaac Rabi ( ; born Israel Isaac Rabi, 29 July 1898 – 11 January 1988) was an American physicist who won the Nobel Prize in Physics in 1944 for his discovery of nuclear magnetic resonance, which is used in magnetic resonance imaging.  He was also one of the first scientists in the United States to work on the cavity magnetron, which is used in microwave radar and microwave ovens.

Ettore Majorana: Ettore Majorana ( ; ] ; born on 5 August 1906 – probably died after 1959) was an Italian theoretical physicist who worked on neutrino masses.  On March 25, 1938, he disappeared under mysterious circumstances while going by ship from Palermo to Naples.  The Majorana equation and Majorana fermions are named after him.

Fano resonance: In physics, a Fano resonance is a type of resonant scattering phenomenon that gives rise to an asymmetric line-shape.  Interference between a background and a resonant scattering process produces the asymmetric line-shape.  It is named after Italian-American physicist Ugo Fano, who gave a theoretical explanation for the scattering line-shape of inelastic scattering of electrons from helium; however, Ettore Majorana was the first to discover this phenomenon.  Because it is a general wave phenomenon, examples can be found across many areas of physics and engineering.

Saint Paternian: Paternian or Paternianus (Italian: "San Paterniano" ) is the name of an Italian saint.  There are two figures, "Paternian of Bologna" and "Paternian of Fermo", who are considered to be the same person.  The first was bishop of Bologna from around 450 to 470.  The second was a native of Fermo who escaped to the mountains during the persecutions of Christians by Diocletian.  He then became bishop of Fano after being appointed to this position by Pope Sylvester I.

Fano factor: In statistics, the Fano factor, like the coefficient of variation, is a measure of the dispersion of a probability distribution of a Fano noise.  It is named after Ugo Fano, an Italian American physicist.

Soncino family (printers): The Soncino family (Hebrew: משפחת שונצינו‎ ) was an Italian Ashkenazic Jewish family of printers, deriving its name from the town of Soncino in the duchy of Milan.  It traces its descent through a Moses of Fürth, who is mentioned in 1455, back to a certain Moses of Speyer, of the middle of the 14th century.  The first of the family engaged in printing was Israel Nathan b. Samuel, the father of Joshua Moses and the grandfather of Gershon.  He set up his Hebrew printing-press in Soncino in the year 1483, and published his first work, the tractate Berakot, February 2, 1484.  The press was moved about considerably during its existence.  It can be traced at Soncino in 1483-86; Casal Maggiore, 1486; Soncino again, 1488–90; Naples, 1490–92; Brescia, 1491–1494; Barco, 1494–97; Fano, 1503-6; Pesaro, 1507–20 (with intervals at Fano, 1516, and Ortona, 1519); Rimini, 1521–26.  Members of the family were at Constantinople between 1530 and 1533, and had a branch establishment at Salonica in 1532–33.  Their printers' mark was a tower, probably connected in some way with Casal Maggiore.

Robert Pound: Robert Vivian Pound (May 16, 1919 – April 12, 2010) was an American physicist who helped discover nuclear magnetic resonance (NMR) and who devised the famous Pound–Rebka experiment supporting general relativity.  He became a tenured professor of physics at Harvard without ever having received a graduate degree.

Enrico Persico: Enrico Persico (August 9, 1900 – June 17, 1969) was an Italian physicist notable for propagating the field of quantum mechanics in Italy.  He was a professor at the University of Turin and is also notable as the doctoral advisor of Ugo Fano.

Constitutiones Sanctæ Matris Ecclesiæ: The Constitutiones Sanctæ Matris Ecclesiæ (English: Constitutions of the Holy Mother Church ), informally known as the Constitutiones Aegidianae (English: "Egidian Constitutions", Italian: "Costituzioni egidiane"), were six books of law which formed the first historic constitution of the Papal States.  They were redacted at Fano by Cardinal Albornoz between 29 April and 1 May 1357 at an assembly of all the vicars of the pontifical territories.
