Beginning of ReadMe : VI/148 Collision Strengths for [Co II] Forbidden Lines - SS4 (Storey+, 2016) ================================================================================ Collision strengths and transition probabilities for Co II infrared forbidden lines . Storey P.J., Zeippen C.J., Sochi T. <Mon. Not. R. Astron. Soc. 456, 1974-1981 (2016)> =2016MNRAS.456.1974S =2016yCat.6148....0S ================================================================================ ADC_Keywords: Atomic physics Keywords: atomic data - atomic processes - radiation mechanisms: non-thermal - supernovae: general - infrared: general Abstract: The list presents electron collision strengths for the forbidden transitions between the fifteen lowest levels of the singly-ionized cobalt, Co^+^, as a function of the electron energy, in an intermediate coupling scheme using the Breit-Pauli relativistic terms as implemented in an R-matrix atomic scattering code. An atomic target for the R-matrix scattering defined by 26 atomic terms is used in these calculations. The data are particularly useful for analyzing the thermodynamic conditions of supernova ejecta. Description: The data set consists of 105 files which are labeled as 'OMEGA_m_n_CoII.dat' where m=1,2,...,14 and n=2,3,...,15 with m<n. The indices m and n refer to the level index as given in the table below. In each file the first column represents the electron energy in Rydberg and the second column represents the collision strength for the transition between the indicated levels. ------------------------------------------------------- Level Index Level Designation ------------------------------------------------------- 1 [Ar] 3d^8^ a^3^F_4_ 2 [Ar] 3d^8^ a^3^F_3_ 3 [Ar] 3d^8^ a^3^F_2_ 4 [Ar] 3d^7^4s a^5^F_5_ 5 [Ar] 3d^7^4s a^5^F_4_ 6 [Ar] 3d^7^4s a^5^F_3_ 7 [Ar] 3d^7^4s a^5^F_2_ 8 [Ar] 3d^7^4s a^5^F_1_ 9 [Ar] 3d^7^4s b^3^F_4_ 10 [Ar] 3d^7^4s b^3^F_3_ 11 [Ar] 3d^7^4s b^3^F_2_ 12 [Ar] 3d^8^ a^1^D_2_ 13 [Ar] 3d^8^ a^3^P_2_ 14 [Ar] 3d^8^ a^3^P_1_ 15 [Ar] 3d^8^ a^3^P_0_ -------------------------------------------------------
