Transition probabilities of the spectrum of Mn III are calculated
using the orthogonal operator description for both the odd and the
even energy levels.

Note to table2: This system is selected by cutting off the higher energy values
of both the even and the odd system in the final printing procedure; only
log(gf) values larger than -1 are included.

1- 8 F8.3 0.1nm lambda Wavelength (1)
10- 16 F7.5 --- log(gf) Oscillator strength
18- 20 F3.1 --- Jf J-value final state
22- 29 F8.2 cm-1 Ef Energy value final state
30 A1 --- n_Ef [*] Indication known/unknown (2)
32- 39 A8 --- Lf Leading term final state (3)
41- 43 F3.1 --- Ji J-value initial state
45- 53 F9.2 cm-1 Ei Energy value initial state
54 A1 --- n_Ei [*] Indication known/unknown (2)
56- 65 A10 --- Li Leading term initial state (3)
--------------------------------------------------------------------------------
Note (1): 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.
Note (2): 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.
Note (3): The first character of the level name designates the configuration
number:
for the even levels '1' refers to 3d^5 and '2' to 3d^4 4s;
for the odd levels '1' refers to 3d^4 4p.

Note (1): The A-values for the forbidden lines given are restricted to the
magnetic dipole (M1) and electric quadrupole (E2) transitions within
the 3d5+3d4 4s configurations, from levels with an energy of less
than 75,000cm-1 above the ground and with A-values larger than
10-3s-1.
Note (2): The level with the lower J-value is given first in the designation of
the transition.
Note (3): 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.
Note (4): The first character of the level name designates the configuration
number: for the even levels '1' refers to 3d^5 and '2' to 3d^4 4s.
