SAMPLE (20-CA-40,NAT=0.96941). Natural calcium cylindrical M038900100012
target, of diameter 72 mm, length 145 mm, and mass M038900100013
735 g, was enclosed in a sealed plastic bag filled M038900100014
with argon gas. M038900100015
METHOD (TOF) Neutron kinetic energies were determined by the M038900100016
time of flight between the calcium target and the M038900100017
neutron detectors. M038900100018
DETECTOR (SCIN) Organic liquid scintillator NE213. M038900100019
ANALYSIS The absolute numbers of photoneutrons with measured M038900100020
kinetic energy were used to obtain the M038900100021
double-differential reaction cross section. M038900100022
ERR-ANALYS (ERR-S) Statistical errors are given. M038900100023
(ERR-1) The systematic uncertainty was estimated to M038900100024
be equal to 6 %. M038900100025
COMMENT The Ca-40(g,n)Ca-39 reaction cross section has been M038900100026
measured with tagged photons with energies ranging M038900100027
from 31.2 to 102 MeV, for neutron emission angles of M038900100028
45, 60, 75, 90, and 135 deg. Exclusive differential M038900100029
cross sections for the Ca-40(g,n) and Ca-40(g,p) M038900100030
reactions are found to be of a similar magnitude, M038900100031
but are not well predicted by recent random-phase M038900100032
approximation and relativistic direct knock-out M038900100033
calculations. M038900100034
Exclusive differential cross section for the M038900100035
