Energy spectrum as function of sum of kinetic energies of several particles
CP-D/434

We have two comments on Memo CP-D/434:
1) This is an extension of “Energy distribution for a correlated pair” (LEXFOR Secondary
Energy Distributions item.2) to N-particle case, because relative energy Erel is the total
kinetic energies of two particles in their center of mass system (c. m. s.), and M. Meister et al.
considers the total kinetic energies of 3 particles in their c. m. s. (=outgoing 6He or 8He restframe).
Therefore it would be better to keep consistency between two particles case and Nparticles case, for example,- Codes for particles considered (SF7): a+b+… or a/b/… ?
- Heading for the total kinetic energies in their c. m. s.: E, E-CM or E-RL-CM ?
I think the reference frame of kinetic energies (laboratory system, c. m. s. of projectile-target,c. m. s. of particles considered…) should be clarified by heading and/or EN-SEC.
2) JCPRG has compiled similar quantity (Energy spectrum of Coulomb excited outgoingparticle) in E1915.002, in which energy spectrum of Pb(11Be, n+10Be)Pb is given for therelative energy for n-10Be(=total kinetic energies in their c. m. s.). We treated this data as
energy spectrum of outgoing 11Be excitation energy, because total kinetic energy in n-10Be c.
m. s. is equal to excitation energy of 11Be (measured from n-10Be threshold). This could be
another solution for M. Meister et al.
3) Addition of new item for total kinetic energy to LEXFOR is useful. This quantity is often
needed in the compilation of fission measurement, in which some works consider total
kinetic energy of fission fragments (e.g. light fragment and heavy fragment).
