From:
Differential cross section with respect to longitudinal momentum
Subject:
We are compiling two experiments in which fragment longitudinal momentum distributions
are measured from the breakup of secondary beam provided by RIKEN Projectile Fragment
Separator - RIPS - (R. Kanungo et al., Phys. Rev. Lett. 88 (2002) 142502 and T. Suzuki et al.,Phys. Rev. Lett. 89 (2002) 012501). Fragments 15B, 22O and 21O coming from Be(17B,15B)X,C(23O,22O)X, and C(23O,21O)X are detected. In EXFOR, these detected fragments are treated as
residual nuclei. We propose the following code for longitudinal momentum distribution forresidual nuclei:
Dictionary 36 (Quantities)
LP,DP,RSD
DP
Differential cross section with respect to longitudinal secondarymomentum
Also we need to add some flags for unstable nuclei used as beam and detected as outgoing
fragments:

We attach a coding sample of this quantity.
