No - it can be used in the descent but not with the slats extended (due to the exhaust flow). Even so, and albeit with an acceleration, it can still achieve up to 20,000fpm RoD.
It certainly makes for an interesting (and mostly green) view from the flightdeck of a 200ton jet!

411A you are indeed correct it was for the -71 & -73 fitted with the CFM motors, I was flying into Lagos with Southern when the Capt used them and for his trouble got wacked on the back of the head by the FE as He was worried about them stowing and being stuck there, as the flt mech I was not overly happy about the situation either

The Herc K can also do it - the only limitation on use of reverse thrust is a speed one - not above 115kts IIRC. It has been done in the sim to quite dramatic (and controllable) effect (1nm short finals, 5000ft agl, successful landing!)- however, it'd take some cojones to try it in the aircraft....prop hangup, anyone?

Reverse Thrust
The Trident reversed thrust, (outers) could be used anytime, any speed, right down to turning off the runway. Very useful on a shortish runway when you could be pulling reverse in the flare.
There's a YouTube video of a C-130 landing on the USS Forrestal. The comentary mentions that the pilot selected reverse thrust before landing.
Video here: YouTube - C-130 Hercules on an Aircraft Carrier!!
C-130 landing and take-off sequence starts about 2-mins into the video

Bakedwell are you sure that the JT 3s had a in flight reverse capability? as my memory thinks they could not, though no speedbrakes as such they had inboard and out ground/flight spoilers that deployed on touchdown spent many an hour in the german cargo hangar rigging them.

Used to be relatively common procedure on C-130 in Viet Nam...
As mentioned, used during Forrestal trials...
Fairly frowned upon these days as it makes for a rather unpleasant landing!
...overall, not approved however.

Urban Myth?
Even though it's gated through the WoW on Tornado, it's still a bad idea to pre-select thrust-reverse on approach because if you make a hash of the landing, it kicks-in just as you bounce and makes your second landing even heavier!
