Denke constant (hbar = e^2*z0)
Denke constant = (1.602176634 x 10^-19 A-s)^2 * (3.767303134 x 10^2 kg-m^2/A^2-s^3)
Denke constant = 9.670554000 x 10^-36 kg-m^2/s

Denke constant (hbar = e^2/e0*c)
Denke constant = (1.602176634 x 10^-19 A-s)^2 / (8.854187817 x 10^-12 A^2-s^4/kg-m^3) * (2.997924580 x 10^8 m/s)
Denke constant = 9.670554000 x 10^-36 kg-m^2/s

Denke constant (hbar = e^2*u0*c)
Denke constant = (1.602176634 x 10^-19 A-s)^2 * (1.256637061 x 10^-6 kg-m/A^2-s^2) * (2.997924580 x 10^8 m/s)
Denke constant = 9.670554000 x 10^-36 kg-m^2/s

Planck constant (h = hbar/2*alpha)
Planck constant = (9.670554000 x 10^-36 kg-m^2/s) / (2.000000000 x 10^0 rad/sr) * (7.297352566 x 10^-3 sr)
Planck constant = 6.626070150 x 10^-34 kg-m^2/s-rad

Alpha constant (alpha = hbar/2*h)
Alpha constant = (9.670554000 x 10^-36 kg-m^2/s) / (2.000000000 x 10^0 rad/sr) * (6.626070150 x 10^-34 kg-m^2/s-rad)
Alpha constant = 7.297352566 x 10^-3 sr

Denke constant (hbar = 2*h*alpha)
Denke constant = (2.000000000 x 10^0 rad/sr) * (6.626070150 x 10^-34 kg-m^2/s-rad) * (7.297352566 x 10^-3 sr)
Denke constant = 9.670554000 x 10^-36 kg-m^2/s
