neutrons

Institute of Physics SAS, Bratislava, Slovakia

Sr-88 Koehler (2000) 5320 points up to 350 keV

isolated points in the Koehler’s region

Hughes (1950) 1 point at 1 MeV (2.1 mb)

Pd-102 no usable data point

Xe-124 no usable data point

Te-130 many points up to 10 keV

about 40 points 10 keV to 20 MeV (60 mb to 0.6 mb)

about 25 points 10 keV to 6 MeV (shifted by 3 orders - error)

Sm-152 two sets (plus isolated points) 3 keV to 3 MeV (1.5 b to 50 mb)

one set (4 points) 25 keV to 1 MeV (shifted by 3 orders)

Ho-165 several sets of data up to 20 MeV (10 b to 0.7 mb)

one set (5 points) 20 keV to 1 MeV (shifted by 3 orders)

Ir-191 several sets up to 20 (25) MeV

(EXFOR v. 1.62 – June 2004)

THEORETICAL UPDATES:

Varlamov et al., Izv. AN 67 (2003), 656: Y-89 GDR

Varlamov et al.: in INDC(CCP)-440 [IAEA 2004], p. 37: strength f. near Sr, Xe, Ho

Vasileva et al.: Yad. Fiz. 64 (2001), 195: strength f. near A=124, Sm-150, Ir-192

Talou et al.: in Varenna Conf. 2003: Ir-193(n,xn)

Plujko: ND-2004: photonuclear channel and strength f.

Hilgers: ND-2004: Os-192(p,n)Ir-192

COMPUTER CODE USED: M. Herman, EMPIRE-II, v. 2.18 Mondovi (IAEA 2002)

Soon to be released:

M. Herman et al.: EMPIRE-II, v. 2.19 Lodi

A. Koning et al.: TALYS

Data of Bensch et al. (4 points) by error in EXFOR shifted by 3 orders

Data by Bensch et al. (5 points) shifted by an error by 3 orders

The resulting excitation functions of all 7 targets [only 5 shown here, where the experimental data are presented in the 2002 version of EXFOR – the two remaining reactions (on Pd-102 and Xe-124) have been also calculated and the excitation functions have been proposed, but not demonstrated as a plot today] have been prepared as ENDF files ready to be given to the IAEA NDS.
