Description
In table 2 the log(gf) values for the 3d^8^+3d^7^ 4s-->3d^7^ 4p electric dipole (E1) transitions are given. This system is selected by cutting off energy values larger than 120,000cm^-1^ of both the even and the odd system in the final printing procedure; only log(gf) values larger than -3 are included. The first column of this table shows the wavelength obtained from the energy differences between the experimental level values. Wavelengths below 2000 Angstrom are given as vacuum wavelengths and above 2000 Angstrom as air wavelengths. The second column gives the log(gf) values followed by the J-value, energy value and the name of the lower (even) level. The first character of the level name designates the configuration number: for the even levels '1' refers to 3d^8^ and '2' to 3d^7^ 4s; for the odd levels '1' refers to 3d^7^ 4p. An '*' after the energy value indicates that the level is known, in which case the experimental level value is given. When unknown, the calculated energy value is given and used to approximate the wavelength. The A-values for the forbidden lines given in table 7 are restricted to the magnetic dipole (M1) and electric quadrupole (E2) transitions within the 3d^8^+3d^7^ 4s configurations, from levels with an energy of less than 50,000 cm^-1^ above the ground and with A-values larger than 10^-3^s^-1^. The level with the lower J-value is given first in the designation of the transition. The remaining columns are similar to the corresponding ones in table 2. The first character of the level name designates the configuration number: for the even levels '1' refers to 3d^8 and '2' to 3d^7 4s. An '*' after the energy value indicates that the level is known, in which case the experimental level value is given. When unknown, the calculated energy value is given and used to approximate the wavelength.
